Pipe mouth size. In welding to measure out the length of the tube, and then use the pipe knife, cut the size of the pipe.
Cleaning the pipe. As the pipe is metallic in nature, the pipe will be oxidized to produce some waste slag, and some of the waste slag will affect the effect of welding. Therefore, when we use before welding, we should apply abrasive cloth or paper, to grind off the scrap slag inside the pipe.
Use the tube brush to clean the fittings. Cleaning the fittings will make sure the soldered hose is joined with the tin plating.
Get the welding time right. Generally speaking how long you need to weld the pipe, you need the corresponding length of solder.
Use torch heaters. The main reason for using a torch heat pipe is to ensure that the pipe is evenly heated at the weld. The caveat is that when using a torch, make sure that the flame is close enough to cover the entire diameter of the pipe.
